This is caused by either
rushing the process or else by badly designed pots. Go slowly, step
by step, to find the right angle for the pot and the head.
If this occurs during
the water flow, it is most often caused by worry, tension or fear
about the practice. It will go away with practice. If it occurs
sometime after the first trial, it can be caused by not drying the
nose well enough and salty water being left to dry in the sinus
passages or else blowing too hard when changing sides and drying
the nose.
It can sometimes happen
that the ears will pop when doing Jala Neti. Some people get a fright,
and are concerned that it may be something serious but this is nothing
to be concerned about. Such sounds are caused by a change in pressure
in the Eustachian tubes as the water flows past, and are usually
a sign that nasal mucus is clearing and balancing what was previously
blocked.
It can also happen
when blowing out between sides or when drying the nose, and there
is a �squeaky� sound caused by a few droplets of water. After drying
this goes away.
This often occurs during
the first few attempts for those people with very blocked sinuses
or ear passages. They must just bear with it until the warm water
dissolves and removes the excess mucus. Greater relief comes in
the end. One or two pots usually clear it completely.
